What to do when all of a sudden things dont seem to go right anymore or play
up in MM.
The suggested protocol might help, try it each step: if it does not work, move
to the next suggestion:
- Close MM and fire it up afresh.
- Re-start your PC
- Try it on another PC if possible. If it
works there, than it is likely to be PC related and not so much MM related.
- Download and install the latest version
all this: it helps if you can simplify the projects/work in which it happens.
-Remove irrelevant layers, boil it down to one map object specifically if you can.
-Try to replicate it in a new GEO, with one new fresh layer, only with one or two
objects in it. Or use a reduce version of a database if that is involved.
- Try it on an old project that worked in the past.
- If you cant replicate it on
another PC, there is no harm in asking the MM discussion forum to see who might be
able to help you, or knows more.
- If you can replicate it
on another PC (or operating system), and it still occurs in the latest version
which can be downloaded from www.mapmaker.com, than
it could indeed be a glitch in Map Maker: Email the developers.
Common errors &
When you open up an old GEO you get an error message:
Redraw failed .
is what has happened:
A map maker Project (GEO) can consist of several layers, databases and
style files. All your drawings can be stored
all over the place in your PC (or network). The GEO file is just a little txt
file, it is what I call- the shopping list for MM. It is a list to tell
MM to display the files in the same sequence and set-up as when you saved
project. This GEO file, the project, the shopping list, is looking for all files
involved in the location and with the file names they had when you saved your project.
it happens that, in between two map maker session, you rename a folder or one of those
files, or you move a folder into a better directory structure, you might have even deleted
a file. When you open up an old GEO, the shopping list is still looking for the files with
their original name in their original location. And thus MM cant display the file
that now is missing.
Action: OK the messages(s), and
in the project manager, under Files you will see which files are supposed to
be in use, what their original file name was and where the were located.
Something is in a twist, either in MM or in Windows.
Revert to the suggested protocol (see above)
Things that often confuse novice users:
Changed appearance in colour and display
Live layer changes
When you copy a layer into the live
layer, MM pulls that transparency out of the stack and serves it on top so you
can actually draw in it (like what you would do in the paper world). There for this layer
might now suppress all underlying information and show things differently to what you had
before. Passive layers might use different style files and might take their colour-que
from an external database. As soon as you copy this layer into the live layer, several
it loses the external data link
it will use the settings dealing with live layer (Top menu, Edit, Live
layer options, eg: Live layer label options.)
it will start using the project style set.
of colour after a cut
When you cut an 'island' into a polygon, the colours of the polygon might change.
This has to do with the complexity of how Windows builds up and deals with the screen
If this happens go to:
(top menu) File, System set-up, Preferences, Miscellaneous, (scroll down to untick, or
tick the option): Suppress fast poly-polygon drawing.
after introducing a new layer or changing layer sequence
Raster files can be compared with digital photocopies of paper
originals (maps, aerial photography etc) . Like their paper equivalent: they are not
transparent. Any layer below it will not show.
(note: Monochrome bitmaps can be set to become
Translucent in MM and their colour can be changed).
change of translucent polygons
It could be either that:
-you are superimposing another layer with other (translucent) polygons on top of
the first, or
-the bottom layer is a colour raster file, and the colours of the translucent layer
on top interfere (naturally) with it.
If in this last case black lines from the raster file change into an awkward
colour try this setting:
(top menu) File, System set-up, Preferences, Miscellaneous, (scroll down to untick,
or tick the option): Suppress fast poly-polygon drawing.
You were sure you had dome some work in a
layer and you were sure you have saved that work, but now that you revisit this GEO afresh
(say the next day) part or all of it is gone:
only the last few objects that you drew are visible, you probably forgot to copy
the layer with previous work into the live layer. When it came to saving your work you
overwrote your previous work, giving this new layer the same name.
or all is gone you might have saved this live layer with a new name, but you failed to
save your project as well.
Now that you have re-opend the project, the GEO file will only
serve up the old layers, not the last layer which was save with a new name.
mapping is a complex busines, however good or userfriendly software can be: if you need

Instructions, or call for a course.
